Sony FDA-EP18 Eyepiece Cup

It popped right onto my A7III and stays put even after hours of shooting, which is exactly what I needed. The rubber feels slightly tacky, so it grips my glasses without smudging them.

The fit on my a7III is perfectly snug—it slides right in and stays put without any wobble. Makes composing shots through the viewfinder feel much more natural and comfortable.

Lost mine during a hike and this replacement snapped into place instantly, no fiddling or tools needed. The soft rubber edge presses against my glasses without smudging them, which makes long shooting sessions way more comfortable than I expected.
